Wind-Turbine and Wind-Farm Flows: A Review (2019, background): “The length scale of VLSMs can exceed 20δ, where δ is the boundary-layer thickness (Fang and Porté-Agel 2015), and they are very energetic structures since they account for a considerable share of the TKE and shear stress (Kim and Adrian 1999; Guala et al. 2006; Lee and Sung 2011).”
Turbulence Structure in Rough and Smooth Wall Boundary Layers (2006, unknown): “The same technique was used by Guala et al. (2006).”
Simulations of Spatially Evolving Turbulent Boundary Layers up to Reθ = 4300 (2010, background): “Such large-scale turbulent structures have received considerable interest over the last years, both experimentally (e.g. Kim and Adrian, 1999; Guala et al., 2006; Hutchins and Marusic, 2007a) and numerically (del Álamo and Jiménez, 2003; Schlatter et al., 2009); open questions relate to the…”
Velocity statistics in turbulent channel flow up to $Re_{\tau }=4000$ (2014, background): “This behavior has been linked to the influence of outer-scaled eddies, which mainly contain wall-parallel, inactive motions (Kim & Adrian 1999; Guala et al. 2006; Hutchins & Marusic 2007).”
Large-scale influences in near-wall turbulence (2007, background): “Guala et al. (2006) report similar behaviour, noting also a separate dominant scale at zzr/2 of length-scale lx/rz2–3 (where r is the pipe radius).”
Large-scale amplitude modulation of the small-scale structures in turbulent boundary layers (2009, background): “For pipe flows, the energetic footprint of superstructure-type events is evident as even longer-wavelength peaks in the pre-multiplied energy spectra of u fluctuations, termed very large-scale motions or VLSMs (Kim & Adrian 1999; Abe, Kawamura & Choi 2004; Toh & Itano 2005; Guala, Hommema & Adrian ”
Towards Reconciling the Large-Scale Structure of Turbulent Boundary Layers in the Atmosphere and Laboratory (2012, background): “…that are responsible for the very long u structures so evident in the logarithmic region of turbulent boundary layers (they also provide a possible organising motion that could lead to the concatenation of packets/LSM as speculated by Guala et al. 2006; Adrian 2007; Dennis and Nickels 2011b).”
Evidence of very long meandering features in the logarithmic region of turbulent boundary layers (2007, background): “From hot-film measurements in pipe flows, Kim & Adrian (1999) and Guala, Hommema & Adrian (2006) found that streamwise energetic modes can extend up to 12–14 pipe radii, and refer to these as very large-scale motions (VLSM).”
